Scientific paper

The formation and evolution of the large-scale structure in unstable dark matter (UDM) models. The main feature of the models is that galaxy formation stars after decays are discussed. Reasonable agreement was found with the observed picture for models with mass of decaying particles 60-90 eV and decay time (0.3-1.5) x 10 to the 9th yr. Galaxy formation in UDM models starts at z = 3 if products of decays are relativistic at present or at least at z = 6-7 if the products are nonrelativistic.
